PI. 71. — a. sporangia (Philadelphia) ; b. capillitium and spores with fragment 

 of sporangium-wall ; c. capillitium from an irregularly formed sporangium ; 

 d. spore. 



This species when well formed presents a strikingly graceful aspect 

 either in the stage where the sporangia are still unbroken, or when they 

 have expanded in a flow< r-Iike manner to expose the orange trumpet- 

 shaped oolumellae and curious spike-like processes of the capillitium. 

 When development has not been perfect irregular distorted sporangia 

 occur. The type of Physartnn rufibasis Berk. & Br. from Ceylon has 

 open funnel-shaped sporangia on short stout stalks connected below 

 by an ample hypothallus. This is one of the two specimens quoted by 

 Rostafinski as types of his Tilmadoche Mans ; the other is referred to 

 as follows : — " The sjDecimen seen was gathered by Jan Kickx (father) 

 in Flanders, and marked by him Craterium minutum Fr." ; it appears 

 to be the only typical example of the present species yet recorded from 

 Europe. A specimen gathered by 'Sir. W. G. Freeman at Onitcha 

 Olona, Nigeria (B.M. 2349), shows every variety between typical 

 sporangia and net-like plasmodiocarps ; the latter have in part the 

 characteristic capillitium, and in part a capillitium consisting of a close 

 network of orange threads with small and large irregular and branching 

 lime-knots. 



A remarkable form showing close affinity to the present species has 

 been found by Dr. Torrend on the bark and leaves of EucaVpytus 

 globulus in the royal park of Alfieti, Portugal, and has been named by 

 him Physarella lusitanica (Fl. Myx., 173, 1909). The sporangia are 

 subglobose or lenticular, and for the most part are deeply umbilicate 

 above ; in some cases the umbilicus is shallow, in others it is so deep 

 as to be continuous with the stalk ; the capillitium consists of a close 

 network of orange threads with few or many large irregular lime-knots, 

 while in one sporangium it was almost Badhamia-like. If this form 

 should prove constant it may well deserve specific rank.

Genus 8. — CIENKOWSKIA Rostafinski Versuch, 9 

 (1873). Sporangia forming net-like plasmodiocarps. Sporan- 

 gium-wall cartilaginous at the base ; capillitium a loose 

 network of rigid threads with many free, curved, sharp- 

 pointed branchlets, connected with flat perforated calcareous 

 plates attached at their margins to the sporangium-wall. 



1. C. reticulata Rost. I.e. Plasmodium deep orange-red. 

 Sporangia sessile, scattered, forming cylindrical usually 

 branched and net-like plasmodiocarps, 0-5 mm. diam., 

 attached by a narrow basal keel to the substratum, yellow- 

 brown or orange, with pale transverse ridges, blotched with 

 crimson ; sporangium-w all orange-yellow, membranous
